nanotubes 1.14.0
Install the most recent stable version from Bioconductor:
if (!requireNamespace("BiocManager", quietly=TRUE))
install.packages("BiocManager")
BiocManager::install("nanotubes")And load nanotubes:
library(nanotubes)Alternatively, you can install the development version directly from GitHub using devtools:
devtools::install_github("MalteThodberg/nanotubes")If you use nanotubes, please cite the following article:

CAGE Transcription Start Sites (CTSSs), the number of CAGE tag 5’-end mapping to each genomic location data was obtained from the authors of the original study. Remaining data used in the study can be downloaded from GSE70386.
One technical replicate was not included.
Load the data into R to get an overview of the included samples:
